Transcript text: What is the IUPAC name of the following compound?

Solution

Solution Steps

Step 1: Identify the longest carbon chain

The longest carbon chain in the molecule contains five carbons. This forms the parent chain, pentane.

Step 2: Identify the substituent

The molecule has one substituent, a hydroxyl (-OH) group. This makes the molecule an alcohol.

Step 3: Number the carbons

Number the carbons in the parent chain so that the hydroxyl group is on the lowest possible number carbon. In this case, the hydroxyl group is on carbon 2.

Step 4: Combine the name

Combine the name of the parent chain and the substituent to get the IUPAC name. Since the hydroxyl group is on carbon 2, the name is 2-pentanol.

Final Answer: 2-pentanol
